Introduction The 2016 Seedless Watermelon Variety Trial included 35 varieties from ten participating companies. The purpose of this trial was to evaluate seedless watermelon varieties for yield, quality and maturity. Materials and Methods Location Grower’s field (Mineral Springs Field #22) next to the University of Delaware, Carvel Research Center, Gary Calloway, Calloway Farms, cooperating grower. Cultural Practices Grower practices for commercial production were used. The field was fertilized and limed according to soil test results. Preplant fertilizer was 80-31-144-27 (N-P2O5-K2O-S). Black plastic mulch and trickle irrigation were laid on 7’ centers between rye windbreaks. Additional 4-0-8 fertilizer was applied by fertigation during fruiting (additional 20-0-40 N and K2O). There were 35 entries in the trial in 2016. Plants were seeded in the greenhouse on April 4, 2016. Plants were transplanted to the field on May 9, 2016. Field plots were one row (7 ft) wide and 27 ft long. Plots were arranged in a randomized complete block design with three replications. In-row spacing was 3ft or 9 plants per plot. Three plants of the in-row pollenizer variety ‘Sp-6’ were planted in each plot and one between plots in the following arrangement: s 6 s s s 6 s s s 6 s s 6. “6” designates Sp-6 and “s” designates the seedless plants. The border rows next to the drive rows, which separated the replications, were planted in the triploid variety ‘Troubadour’, with Sp-6 as the pollenizers, in the same arrangement as the experimental plots. There were 2 grafted treatments, grafted Fascination at the same planting arrangement and grafted Fascination planted with 7 plants per plot. This is designated as “Grafted Fascination lp” for the lower population. Herbicides used in row middles included Sandea (halosulfuron) 0.75 oz/A + Dual (metolachlor) 1 pt/A + Sinbar (terbacil) 2 oz/A. In addition, Gramoxone (paraquat) 2 qt/A was applied with a hooded sprayer to terminate rye windbreaks. Disease, insect and mite control programs were as follows:

5-31: Provoke (imidacloprid) 1.5 oz./a 6-15: Echo (chlorothalonil) 3 pt/A, Cueva 1.5 pt/A 6-22: Echo 3 pt/A, Cueva 1.5 pt/A Incognito 20 oz/A, Manzate 3 lbs/A 6-29: Echo 3 pt/A, Cueva 1.5 pt/A, Oberon 8 oz/A 7-6: Echo 3 pt/A, Cueva 1.5 pt/A, Zampro 14 oz/A, Portal 1 qt/A 7-13: Echo 3 pt/A, Cueva 1.5 pt/A 7-20: Echo 3 pt/A, Cueva 1.5 pt/A, Revus 8 oz/A 7-29: Echo 3 pt/A, Cueva 1.5 pt/A, Presidio 4 oz/A, Assail 4 oz/A Irrigation was determined by the grower and was the same as the rest of the commercial field. Temperatures during the early growth period were below average and growth was slow in May. Harvest Due to the late spring, plots were not harvested until August. Fruit were harvested three times. The first harvest was on August 2 and 3, the second harvest was on August 10 and 11, and the final harvest was on August 28. The weight of each watermelon harvested was recorded individually. Five marketable watermelons from each plot were cut and evaluated for presence of hollow heart, hard seeds and soluble solids levels. Watermelons were cut lengthwise and then crosswise and the number of hard seeds visible on the surface of the four pieces were counted. Soluble solids were measured using a hand-held refractometer. Hollow heart was rated on a 1-5 scale with 1 being no hollow heart and 5 being severe hollow heart. Results Total yield, marketable yield excluding misshapen culls and fruit less than 9 lbs (Marketable Yield I) and marketable yield excluding misshapen culls, fruit less than 9 lbs and fruit over 24 lbs (Marketable Yield II) are reported in Tables 2 and 3 in both pounds per acre and fruit per acre for each variety. Yields in the trial ranged from 49,686 to 124,647 lbs/A. The highest yielding varieties in the trial in terms of Marketable Yield I in lbs/A were: Maxima, Talca, Premont, 7187, Crunchy Red, Grafted Fascination low population, Road Trip, SV7112WA, Wolverine, and Cut Above. The highest yielding varieties in the trial in terms of Marketable Yield I in fruit/A were: Maxima, Talca, Premont, 7187, Crunchy Red, Grafted Fascination low population, Road Trip, SV7112WA, Wolverine, Cut Above, Unbridled, 7197, Wayfarer, Grafted Fascination, Traveler, ORS 6151, Razorback, and Neptune. The highest yielding varieties in terms of Marketable Yield II in lbs/A were: Talca, Premont, Crunchy Red, Maxima, Grafted Fascination LP, 7187, Wolverine, Road Trip, Cut Above, Unbridled, Wayfarer, and 7197. The highest yielding varieties in terms of Marketable Yield II in fruit/A were: Talca, Premont, Crunchy Red, Maxima, Grafted Fascination LP, 7187, Wolverine, Road Trip, Cut Above, Unbridled, Wayfarer, 7197, Grafted Fascination, Razorback, Neptune, ORS 6151, Poseidon, and ORS 12154a.

Table 4 reports the percent of total harvest for each harvest. The following varieties produced more than 50% of their yield on the first harvest: SV7112, Unbridled, 7197, Wayfarer, Traveler, Excursion, Secretariat, and Sweet Dawn. Those varieties with greater than 35% of their yield on the last harvest were: Maxima, Premont, Low Population Grafted Fascination, Grafted Fascination, ORS 6042b, Fascination, and ORS 12154A. Grafted Fascination (using interspecific Cucurbita rootstock) planted at 78% of population of ungrafted Fascination yielded 22% higher. Fruits were heavier and there were significantly more fruits in the second and third harvests compared to ungrafted Fascination. Yields of grafted Fascination planted at the same population as ungrafted Fascination were not statistically different from ungrafted plots. Table 5 lists the varieties according to average fruit weight and gives the percentage of fruit in each of four weight classes: 60 count (9.0-13.5 lbs), 45 count (13.6-17.5 lbs), 36 count (17.6-21.4 lbs) and 30 count (>21.5 lbs). Table 6 lists the varieties according to average fruit weight and gives the yield of fruit in each of the weight classes. Maxima, ORS 6042b, and SV 7112 had the largest average fruit size while Wayfarer, ORS 12154b, and Cut Above had the smallest fruits. ORS 12154a, Wayfarer, Cut Above, Poseidon, and ORS 12154b produced over 50 % of the melons harvested for those varieties in the 60 count class. Joy Ride, ORS 6151, Unbridled, Road Trip, ungrafted Fascination, and Secretariat also produced high numbers of fruit in the 60 count class. Those varieties with more than 40% of the fruit harvested in the 45 count class included Summer Breeze, Crunchy Red, Charismatic, Tri-X 313, Sweet Dawn, Grafted Fascination LP, Kingman, Sugar Fresh, USA90020, 7197, Warrior, Premont, Captivation, Embasy, Razorback, Grafted Fascination, ungrafted Fascination, and Neptune. Varieties with high numbers of 36 count fruit were Maxima, ORS 6042b, Excursion, SV7112, and Talca. Maxima and ORS 6042b produced over 30% in the 30 count class. Table 7 lists the varieties according to their soluble solid measurements. Soluble solids averages are based on a 15-fruit sample (5 fruit per replication). There were significant differences in soluble solids among the varieties. Summer Breeze, Joy Ride, Road Trip, 7197, SV7112, Poseidon, Charismatic, Crunchy Red, ORS 6042b, Talca, and Sugar Fresh had the highest soluble solids level. All of the varieties had average soluble solids of over 10% with the exception of Neptune and ORS 12154a. Table 8 lists the varieties according to average severity of hollow heart. Hollow heart averages are based on a 15-fruit sample (5 fruit per replication). No hollow heart was observed in Neptune, Premont, SV7112, Sweet Dawn, Talca, Traveler, and ungrafted Fascination. Low population grafted Fascination had high levels of hollow heart. Those additional varieties with one or more fruit with major or severe hollow heart (5-13% unsaleable) were USA90020, Charismatic, Embasy, Grafted Fascination, Joy Ride, ORS 6151 and Wolverine.

Table 9 lists the varieties according to the percent of fruit with enough hard seeds to render them unmarketable. Neptune, Sweet Dawn, Grafted Fascination low population, Fascination, ORS 12154a, Exclamation, Embasy, Wayfarer, and Grafted Fascination all had significant numbers of fruit over standard for hard seed.
